860. Phylloscopus luscatus fuscatus

(860) Phylloscopus fuscatus fuscatus (Blyth).
THE INDIAN DUSKY WILLOW-WARBLER.
Phylloscopus fuscatus fuscatus, Fauna B. I., Birds, 2nd ed. vol. ii, p. 461.
This Willow-Warbler breeds in Siberia from Lake Baikal to the Amur and Japan and almost certainly considerably South into Central Asia and Tibet. I have twice had nests, eggs and skins of this bird sent me from Tibet, in both instances the birds being trapped off the nest. Nests and eggs are so typical of the birds breeding in Siberia that I think in these instances there is no doubtas to their being correct. Two years elapsed between the taking of the first and second nest, and the skins, though mere remnants, could only have been this bird or armandii, and the lower parts were too deep a buff to have been the latter bird. The nests which were taken on the 9th and 26th May each contained four eggs. They were balls made almost entirely of dry moss, lined first with grass-stems and then with wool and feathers mixed. Both were placed almost on the ground in low Willow-scrub by streams, at elevations of about 13,000 and 14,000 feet.
The eggs are pure white, in shape broad, pointed ovals and in texture unlike any Phylloscopus egg, but very like that of the egg of Acanthopneuste nitidus viridanus, fine, but not very close, with, a dull surface and very fragile.
Seventeen eggs average 16.8 x 12.5 mm. : maxima 18.6 x 13.3 mm. ; minima 15.8 x 12.3 and 17.1 x 12.1 mm.
